"""Get a path to the directory of this script.
By default, the canonical path (symlinks resolved) will be returned. In some
environments the canonical directory is not sufficient because different
parts of the SDK are referenced by symlinks, including this very module's
file. In this case, the non-canonical path to this file's directory will be
returned (i.e., the directory where the symlink lives, not the directory
where it points).
Args:
sibling: Relative path to a sibiling of this module file. Choose a sibling
that is potentially symlinked into the parent directory.
Returns:
A directory name.
Raises:
ValueError: If no proper path could be determined.
